The arrest stems from a Jan. 9 interaction, when authorities say Ekwonna met with a 15-year-old girl on the social media app Tagged. The teen agreed to meet with the cop and engage in sexual activity in exchange for money, according to police.

Once the deed was done, Ekwonna held a gun to the 15-year-old girl and demanded that she return his money, authorities charge. The girl did so and Ekwonna left.

Police became aware of the teen March 13 after the Department of Homeland Security notified them over concerns of human trafficking.
